ROLLING-MILL.

SPECIFICATION forming part of Letters PatentNo. 413,141, dated October 15, 1889. Application filed August 19, 1889. Serial No. 321,261. (No model.)

To all whom it may concern.-

Be it known that I, PATRICK F. HANLEY, a citizen of the United States, residing at Homestead, in the county of Allegheny and State of Pennsylvania, have invented or discovered a certain new and useful Improvement in Rolling-Mills, of which improvement the following is a specification.

In Letters Patent No. 352,745, dated November16, 1886, and in an application, Serial No. 296,571, filed January 17, 1889, I have described and claimed certain improvements in feed-tables for rolling-mills, consisting in the mechanism for shifting said tables laterally and vertically in accordance with the requirements of the mill, such improvements being effected by means of one or more fluidpressure cylinders located on the table-supporting carriage through suitable interposed mechanism; and in said application I have also described and claimed the arrangement of two similarlyanoving tables on opposite sides of a pair of rolls, the simultaneous movemen ts of both tables being effected by a fluid pressure cylinder located on the carriage of one of the tables and operating through suitable interposed mechanism.

The object of the invention described herein is to provide for the simultaneous vertical and lateral adjustment of feedtables arranged on opposite sides of a pair or train of rolls by means of fiuid-pressure cylinders located in suitable relation to each table, operating through a suitable system of shafts, and controlled in their operation from a pulpit or platform attached to one of the table-supporting carriages.

In general terms, the invention consists in the construction and combination of mechanical devices or elements, all as more fully hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of a rolling-mi1l plant embodying my invention, a part of one of the tables being broken away. Fig. 2 is a sectional elevation of one of the tables and its carriage, and Fig. 3 is a sectional elevation showing the arrangement of gearing when the cylinders are located as represented in dotted lines in Fig. 1.

In the practice of my invention two pairs or lines of rails 1 and 1 are arranged on each side of the rolls A parallel with the axes of said rolls, as shown in Fig. 1. On. these rails are mounted suitable trucks having frames 2 and 2" secured thereto, said trucks and frames forming carriages for the tables 3 and 3. The tables 3 and 3 consist, as set forth in Letters Patent No. 352,748, of side plates having feed-rolls mounted therein, said rolls being driven by a suitable train of gearing secured to the ends of said rolls. As stated in said Letters Patent, the tables are pivoted near the outer ends to posts projecting up from the carriages, so as to permit of the vertical adjustment of the ends of the tables adjacent to the rolls A. For effecting this vertical movement curved racks t 4: are se cured to the tables near their inner ends,and pinions 5 5 on the shafts 6 6 intermesh with said racks, as shown in Fig. 2. 5 5 are so keyed to the shafts as to rotate therewith while free to move therealong as the carriages are shifted laterally, as will be hereinafter described. It is preferred, in order to prevent any twisting of the tables, to employ two racks, one secured to each side plate of each table, and two pinions, which are held in alignment with the racks by the sides of the carriages and by collars 7, interposed between the pinions and surrounding the shafts, which are mounted at the ends in bearings 8 8 and 9 9, their middle portions being supported by the sides of the carriages. On the'shafts 6 6 are secured beveled pinions 10 10, intermeshing with correspondingly-shaped pinions 11 11 on the ends of the shaft 12, which is also mounted in the bearings 8 8. On the shaft 12 is keyed a pinion 13, with which a rack 14: intermeshes, said rack being connected to the piston-rod 15 of the fiuid pressure cylinder 16.

The lateral movements of the carriages are effected by pinions 17 17 on the shafts 18 18, mounted in suitable bearings l0ngitudi nally of the carriages, said pinions engaging racks 19 19 arranged between the lines of rails 1' 1, as shown in Fig. 1. On the inner ends of the shafts 17 17 a are secured the beveled pinions 20 20, adapted to intermesh with similar pinions 21 21, so keyed to the The pinions shafts 22 22 as to move freely along the shafts while rotating therewith. The pinions 21 21 are held in proper engagement with the pinions 2O during the movement of the carriages by means of sleeves 23 23, surrounding the shafts 22 22 and interposed between the pinions and the sides of the carriages, as shown in dotted lines in Fig. 1. The shafts 22 22 are mounted at their ends in bearings 24 24 and 25 25,and on said shafts are keyed the beveled pinions 26 26, intermeshing with correspondingly-shaped pinions 27 27 on the shaft 28. This shaft is mounted at its ends in the bearings 24 24, and has keyed thereto a pinion 29, adapted to engage the rack 30, connected to the pistonrod 31 of the fluid-pressure cylinder 32.

On one of the carriages, and preferably 'near its outer end, is secured a platform or pulpit 33, on which the operatorstands while shifting the levers 34 and 35, controlling the valve mechanisms 36 and 37 of the cylinders 16 and 32 through the medium of the rods 38 and 39, as shown in Fig. 1. Any other arrangement of the valves and their operating mechanisms whereby the valves may be controlled from the pulpit 33 may be employed.

As shown in dotted lines in Fig. 1, the drivingrshafts 12 and 28 and the beveled pinions, whereby said shafts transmit motion may be dispensed with, the fluid-pressure cylinders 16 and 32 being arranged at right angles to the shaftsti 6 and 22 22, on which in such case pinions 13 13 and 29 29 will be keyed and operated by racks 14 and 30.

\Vhile preferring to employ curved racks and pinions for raising and lowering the tables, as hereinbefore described, it will be evident to those skilled in the art that the bellcrank levers described and shown in Letters Patent No. 352,748 and in the application hereinbefore referred to may be employed.

I claim herein as my invention 1. In a rolling-plant, the combination of a laterally-moving carriage, a table provided with feed-rolls pivoted thereto, a shaft having a pinion keyed thereto, a fluid-pressure cylinder independent or outside of the carriage and adapted through interposed gearing to rotate said shafts, and stationary racks with which said pinion intermeshes, substantially as set forth.

2. In a rolling-mill plant, the combination of a carriage, a table provided with feed-rolls pivoted thereto, a curved rack attached to said table, a shaft having a pinion keyed thereto engaging the rack, and a fluid-pressure cylinder located outside of the carriage and adapted through interposed gearing to rotate the shaft, substantially as set forth.

3. In a rolling-plant, the combination of rolls, two carriages arranged on opposite sides of the rolls, tables pivoted to said carriages, racks arranged parallel with the axes of said rolls, shafts mounted on the carriages and provided with pinions engaging the racks,

.and a fluid-pressure cylinder independent of or outside of the carriages and adapted through interposed gearing to rotate said shafts, thereby effecting a simultaneous lateral movement of both carriages, substantially as set forth.

4. In a rollingmill plant, the combination of rolls, two frames or carriages arranged 011 opposite sides of the rolls, tables pivoted to the carriages, curved racks securedto the tables, shafts having pinions keyed thereto engaging said racks,.and a fluid-pressure cylinder located outside of the carriages and adapted through interposed gearing to rotate said shafts, thereby moving both tables simultaneously, substantially as set for 5,121.

5. In a rolling-plant, the combination of rolls, twoframes or carriages arranged on opposite sides of the rolls, tables pivoted to the carriages, fluid-pressure cylinders adapted by interposed gearing to shift the carriages and tables, a platform secured to one of the carriages, and levers connected to the valve mechanism of the cylinders and located in convenient proximity to the platform, substantially as set forth.

In testimony whereof I have hereunto set my hand.

PATRICK F. HANLEY.
